Phys.org / Milky Way is embedded in a 'large-scale sheet' of dark matter, which explains motions of nearby galaxies
Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local Group of galaxies (which ...
Phys.org / Superfluids are supposed to flow indefinitely. Physicists just watched one stop moving
Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid. Quantum matter, however, can behave very differently. In the early 20th century, researchers discovered ...
Phys.org / World not ready for rise in extreme heat, scientists say
Nearly 3.8 billion people could face extreme heat by 2050 and while tropical countries will bear the brunt cooler regions will also need to adapt, scientists said Monday.
Phys.org / Saltier seas in spring double the chance of extreme El Niño events, study finds
Stronger El Niño events are more likely when springtime surface waters in the western Pacific Ocean become unusually salty, a new study in Geophysical Research Letters suggests. Traditionally, scientists have focused on ...
Dialog / The hidden physics of watersheds: Why some are more sensitive to climate variability than others
Water is everywhere, from the snowpack in the mountains to the tap in our kitchens. But while we often think about rainfall and snow as the main drivers of our water supply, it turns out that something we rarely see has just ...
Phys.org / Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limitations
Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in 3D micro- and nanofabrication. ...
Phys.org / Burning trees to help the planet? South Florida tries new climate tech solution
In lush South Florida, trees and bushes grow all year round. And that means yard waste and dead trees never stop piling up. But leaving them in a landfill is a climate-warming issue. Two South Florida governments think they ...
Phys.org / The infant universe's 'primordial soup' was actually soupy, study finds
In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a "quark-gluon plasma" that lasted for only a few millionths ...
Phys.org / Deforestation is drying out the Amazon rainforest faster than previously thought
Deforestation is having a more devastating effect on the Amazon rainforest than earlier data suggested. While cutting down large swaths of trees destroys vital habitats, it also harms the region's ability to generate its ...
Phys.org / Aging populations could cut global water use by up to 31%, study finds
Across the world, water scarcity is emerging as one of the most pressing challenges of the 21st century. Climate change is pushing rivers and aquifers into unprecedented extremes, droughts and floods are intensifying, and ...
Phys.org / Higher water levels could turn cultivated peatland in the North into a CO₂ sink
In its natural state, peatland is one of the largest carbon stores in nature. This is because the soil is so waterlogged and low in oxygen that dead plant material breaks down very slowly. The plants do not fully decompose ...
Phys.org / The circular economy may not be taking off: Here are six ways stakeholders can make it happen
Around the world, governments and businesses are talking more and more about the need to move from today's "take, make, waste" economy to a circular one, where products are designed to last, materials stay in use, and waste ...
